shaking table test model
hi guys,
as you may be aware, the recently lunched swfc (shanghai world financial centre) tower and cctv tower in shanghai and beijing, have been studied through 1:50 and 1:35 scaled models on shaking table to predict a more realsitic behaviour of these structures under the earthquake.
i was wondering if any of you has got any detailed information about how this study has been done and how the  strength of materials and other stuff have been scaled down.
regards,
sam
